Please answer these questions before submitting your issue. Thanks!

go version go1.8.1 windows/amd64

What operating system and processor architecture are you using (go env)?

set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=C:\Users\CodeHz\go
set GORACE=

What did you do?

go get github.com/go-gl/gl/v4.5-core/gl

If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

What did you expect to see?

Install successful

realgcc.exe: fatal error: no input files
compilation terminated.

ANY project contain cgo would not build.
For detect problem I exec below command in cmd

> go build -work -x

# github.com/go-gl/gl/v4.5-core/gl
realgcc.exe: fatal error: no input files
compilation terminated.

And C:\Users\CodeHz\AppData\Local\Temp\go-build075421998\github.com\go-gl\gl\v4.5-core\_obj is empty.
But if I removed -I "C:\\Users\\CodeHz\\AppData\\Local\\Temp\\go-build075421998\\github.com\\go-gl\\gl\\v4.5-core\\gl\\_obj\\" in the last command,

> "C:\\Go\\pkg\\tool\\windows_amd64\\cgo.exe" -objdir "C:\\Users\\CodeHz\\AppData\\Local\\Temp\\go-build075421998\\github.com\\go-gl\\gl\\v4.5-core\\gl\\_obj\\" -importpath github.com/go-gl/gl/v4.5-core/gl -- -g -O2 -DTAG_WINDOWS conversions.go debug.go package.go procaddr.go

And it can build the obj file.

Fixed.

> where gcc
C:\Program Files\Haskell Platform\8.0.2\mingw\bin\gcc.exe  //<- gcc 5.2 and missing some feature
E:\mingw-w64\x86_64-6.3.0-posix-seh-rt_v5-rev2\mingw64\bin\gcc.exe // <- gcc 6.3.0 and worked

I just adjust the order of PATH
